Dimension X was first heard on NBC April 8, 1950, and ran until September 29, 1951.
Strange that so little good science fiction came out of radio; they seem ideally compatible, both relying heavily on imagination. Some fine isolated science fiction stories were developed on the great anthology shows, Suspense and Escape. But until the premiere of Dimension X -- a full two decades after network radio was established -- there were no major science fiction series of broad appeal to adults. This show dramatized the work of such young writers as Ray Bradbury, Robert (Psycho) Bloch, Robert Heinlein, Isaac Asimov, and Kurt Vonnegut. In-house script writer was Ernest Kinoy, who adapted the master works and contributed occasional storied of his own.
Dimension X was a very effective demonstration of what could be done with science fiction on the air. It came so late that nobody cared, but some of the stories stand as classics of the medium. Bradbury's "Mars Is Heaven" is as gripping today as when first heard. His "Martian Chronicles" was one of the series' most impressive offerings.
Dimension X played heavily on an "adventures in time and space, told in future tense" theme. Actors who worked regularly on the show included Joe Di Santis, Wendell Holmes, Santos Ortega, Joseph Julian, Jan Miner, Roger De Koven, John Gibson, Ralph Bell, John Larkin, Les Damon, and Mason Adams. It was directed by Fred Weihe and Edward King. The deep-voiced narrator was Norman Rose.
The series played heavily on the "X" factor in the title, as did X Minus One a few years later. The signature was boomed out of and echo chamber as "DIMENSION X X X X X x x x x x . . . "

OTRR Maintained Set -- This set contains all known episodes in the best available audio condition with the most accurate dates and titles known to be in general circulation and based on current research at the time of release. Replaces OTRR Certified Accurate and OTRR Certified Complete.
OTRR Non-Maintained Set -- A collection of shows that has not gone through the OTRR Maintenance process.
Pre-2019 OTRR Definitions:
OTRR Certified Accurate -- A series that was "Certified Accurate" indicated that all the episodes were properly identified and labeled based on current information but that the series did not contain all known extant episodes.
OTRR Certified Complete -- A series that was "Certified Complete" achieved the highest level of certification available under the OTRR Certified Standards. This certification level implied that all the files in the series were "Certified Accurate" and also indicated that the series was as complete as possible and included all circulating episodes.
OTRR Non-Certified -- A collection of shows that has not gone through the OTRR Certification process.
Also, beginning in 2019, the version numbers of our OTRR releases changed format -- instead of v1.0 or v2.1, we are now using a version number that reflects the year and month the set was released. The format used is a two-digit year followed by a two-digit month. For example, "v1906" indicates a set that was released in June 2019, or "v1910" indicates a set released in October 2019.
NOTE: There are no passwords for any of our ZIP files. If you are prompted for a password, before downloading the file again, try unzipping the file into a shorter full folder path name -- for example, unzip to "C:\" instead of "C:\Documents and Settings\your_Windows_ID\some_other_folder\". Sorry, some of our releases contain long folder and file names, which sometimes manifests itself on the Windows platform as prompting for a password for the ZIP file. Or try renaming the ZIP file itself to a shorter name before unzipping.
"With Folded Hands" and "The Castaways" are both great. I also like "The Embassy" and "Mars Is Heaven." In fact, I think this is my favorite version of "Mars is Heaven."

Listen to history happening
@ 23:00 on #12 and at the beginning of #13 you can hear a news broadcast cut away as America enters the Korean war 50-06-24 and 50-07-01.
That's pretty thrilling. In the middle of tales about atomics and ro-bits and missions to the moon.
I love listening to these tales. Some of them are really stark.

An excellent radio series
Dimension X and X Minus one, are probably the two best science fiction shows to be on what we now consider old time radio, in part because they were were well written, well crafted, well performed, as well as being first. Lesser shows could have reduced science fiction to a footnote in the history of old time radio. Yes, there were occasional weak episodes, but that was more in the sense they were weak against the high standard they set for themselves, not weak against other science fiction series. The writing for both series wasn't as strong as, say, Frontier Gentleman or Gunsmoke, or possibly The Great Gildersleeve, Jack Benny or Barry Craig because those shows had a continuing cast which you could relate to. And, there was an overlap of episodes. But, for those with the adventure of mind and imagination that only science fiction can bring to mind, travel to space and the future, even as dated as some of the shows may be, they were almost as good (and to many people, better) than curling in a corner with the latest paperback or monthly magazine of featuring the same story.
The bad part of science fiction, of course, is that ever since 1969, no one can ever write about what it will be like to land on the moon... Still, these stories and performances stand the test of time.

Loved it down loaded half of them at the Library and rusged back the next day to get the rest. I must up load “Journey into Space” also from the 50's and at 20 episodes per story it seems to happen in real time in “The Red Planet” they get to Mars until episode 10!
As Dim X is a weekly show how come Wheaty's Week lasts for three episodes? Listening to them one after another it felt like the Wheaty people where trying to take over my mind – eat them at 7, still spewing at 11.

I admit that I don't have all of these episodes, but it's funny when you stop to think about it, that the producers of this 1950's radio program considered that "future tense" (at least in some of the episodes that I have) only extended as far ahead as the 1990's (this is 2010), and many of them have some sort of apocalyptic-gloom-and-doom ending as their theme, none of which, of course, has happened in real life. Having said that, it sounds sort of like all this talk about "global warming", although I don't claim to be a science expert.

So far I've gotten through about half the episodes, and I can safely say that this is an excellent series. I specially like episode 13. It's an almost perfect prediction of the internet and modern computers.
On an interesting side note: episode 12 and 13 are interrupted by a news bulletin about the start of the Korean war.
